all school should use this book becuase it promte no animal buasece all the animal is just a costume but the then agian it is a bit Out dated and some of the things ( not the animals) i think are a bit offsensive to some people like the blackface makeup and mistral stuff i just feel is wrong do those kinda to do things in this day and age i am glad that is do not exsit in this day and age so mayabe all school should not use all part of the book cuase there are some parts that some people might find a bit offseive, However IF they decied to use some of offesnive stuffs they have to make some serious updates or editing to make it less offesnvie or hurtful to other people of differnt enthics and relventant to this day and age and in order to avoid backlash from social media, PTA, and parents like zero use of blackface and title updates of some of the acts and maybe update some part of show to make it relevant to this day and age and avoid acts like the "Negro Minstrels" (sorry for saying the n-word) becuase acts like those is offesnive and hurtfull to people of differents enthics so avoid using those acts and if they use the siamese twin bit they have to identcial so no blackface as well and maybe update the title to conjoined twin or somthing. ( ok those advice are just being a concern citizen making sure that if this book is use the teachers or school they would make sure to edit or update some of the offessnive stuffs so other schools use the less offessnive version of this book inthe future) so i'm sorry for the part about outdated parts but that is how i feel
